Fundamental Observation
Fundamental Observation is the flagship of the Bottle Logic barrel programme, an imperial stout released as an annual vintage since 2015. The beer ages in bourbon barrels and is conditioned on Madagascar vanilla beans before blending. The current vintage opens with vanilla and oak, followed by dark chocolate, bourbon sweetness and warm baking spice. Earlier vintages recalled brownie batter, cookie dough, caramel and brûléed brown sugar. The body is dense and viscous, and the finish leaves vanilla and barrel character side by side with a noticeable warmth.
